Controlled Cutting Through Tiles & Abrasive Materials

Drilling clean openings through tile, fibre cement, glass or stone calls for a different cutting edge than you'd use on steel or timber. Sutton diamond grit holesaws are designed for Australian trades working with hard & abrasive materials including ceramic & porcelain tiles, marble, soft stone, fibre cement, fibreglass, hard plastics & plexiglass. Sutton's H115 range uses a diamond-grit cutting edge with a 25mm cutting depth, giving installers, renovators & maintenance crews a purpose-built option where conventional toothed holesaws aren't the right choice.

Choosing the right Sutton diamond holesaw involves more than matching the required diameter. Material, cutting depth, compatible arbor or guide, drilling equipment, low cutting speed & continuous water cooling all form part of the setup. Sutton specifically warns that overheating can destroy the diamond bond, making heat control an important part of correct H115 use rather than an optional extra.

What Are Sutton Diamond Grit Holesaws?

A diamond-grit holesaw cuts differently from a conventional toothed holesaw. Instead of relying on individual HSS or carbide teeth, abrasive diamond grit around the cutting edge works progressively through suitable hard materials as the cutter rotates.

That distinction becomes important when working with porcelain tile, ceramic, fibre cement, glass or marble. These surfaces can be hard, brittle or highly abrasive, so the cutter needs to suit the material rather than simply match the required hole diameter.

Sutton's H115 diamond-grit holesaws feature:

► Diamond grit for hard tiles & abrasive materials
► 25mm cutting depth
► Cut-out slots for heat dissipation & easier plug removal
► International thread standard for compatible arbor systems
► Individual cutters & application-focused sets

How the cutter is used matters just as much as its construction. Sutton specifies slow-speed operation under a constant flood of water, with overheating capable of damaging the diamond bond.

This isn't a cutter you fit to a drill & simply run flat-out. Diamond grit, low speed, water cooling & controlled feed work as one cutting system.

Why Choose Sutton Diamond Grit Holesaws?

Hard surface materials present a different cutting problem from steel or timber. Ceramic & porcelain tiles can be brittle, fibre cement is highly abrasive, while glass, marble & similar materials demand controlled cutting if the finished surface is going to stay intact.

Sutton diamond-grit holesaws are designed around those requirements. The abrasive cutting edge works progressively through compatible materials while continuous water helps control temperature at the cutting area. For trades working across bathrooms, kitchens, fit-outs, cladding, fibre-cement installations & maintenance jobs, the H115 range provides a clear alternative to conventional toothed holesaws.

Diamond Grit for Hard & Abrasive Materials

Sutton lists the H115 range for suitable applications including:

► Ceramic tiles
► Porcelain tiles
► Glass
► Laminates
► Fibreglass
► Hard plastics
► Plexiglass
► Fibre cement
► Ceramics
► Graphite & carbon
► Marble
► Soft stone

The common relationship is the material itself. These are applications where abrasive cutting technology makes sense & where selecting the cutter around the substrate is more useful than treating every hard surface as the same job.

Water Cooling Is Part of the Setup

Continuous water isn't simply there to clean up the cutting area. Sutton specifies a constant flood of water to prolong cutting life & warns that overheating can destroy the diamond bond.

That makes cooling part of correct tool use.

Before starting, plan how water will reach the cutting edge continuously while keeping the overall drilling setup appropriate for the work area & equipment being used.

Cut-Out Slots Help Manage Heat & the Plug

Sutton incorporates cut-out slots into the H115 design to assist heat dissipation & make plug removal easier once the opening has been completed.

Those slots support the process but don't replace water cooling. Temperature still needs to be controlled throughout the cut.

Common Applications

Bathroom & Kitchen Tile Penetrations

Bathrooms, kitchens & wet areas regularly require openings through finished tile for pipework, taps, fittings, cable routes & other services. These are high-consequence cuts because a misplaced or damaged opening may mean replacing a finished tile rather than simply trying again on another piece of sheet metal.

For plumbing-related installations,  Plumbing Fixtures & Accessories provides a relevant pathway into the components that often determine where these penetrations need to be made.

Before cutting, confirm the fitting location, finished hole diameter, tile material & what's sitting behind the surface.

Fibre Cement Sheet & Building Products

Fibre cement is widely used across building, renovation & cladding work, but its abrasive nature can be demanding on conventional cutting edges. Sutton specifically includes fibre cement within the H115 application range.

For trades working across sheet installation, framing & general construction,  Carpentry Tools & Fasteners connects the holesaw application with the wider building workflow.

Glass & Fibreglass

Sutton also lists glass & fibreglass among the suitable materials for H115 diamond-grit holesaws. These applications reward preparation: accurate positioning, stable workholding, controlled speed & continuous cooling are more useful than trying to force the cutter through quickly.

Marble & Soft Stone

Round penetrations may be required through suitable marble or soft-stone surfaces for plumbing, fittings or other services. Sutton includes both materials within the H115 application range, but material identification remains important because not every type of stone or masonry should automatically be treated as an H115 application.

Hard Plastics & Plexiglass

Diamond-grit holesaws aren't limited to mineral-based surfaces. Sutton also identifies hard plastics & plexiglass among the intended applications, giving the range relevance across fabrication, fit-out & maintenance work involving brittle or abrasive sheet materials.

Product Selection Guide – Match the Cutter to the Surface

The finished opening may look straightforward, but hard surfaces leave less room for poor preparation. Start with the material & required hole rather than simply choosing a diamond cutter because the substrate feels difficult to drill.

Identify the Material First

Ceramic tile? Porcelain? Fibre cement? Glass? Marble? Fibreglass?

Identify the substrate before selecting the cutter. This confirms whether the H115 diamond-grit system belongs on the job in the first place.

Don't assume every hard surface requires the same diamond cutting system.

Confirm the Finished Hole Diameter

Work backwards from the component passing through the opening. Pipework, fittings, conduit, cable entries & other hardware may require a specific clearance rather than the nearest convenient holesaw size.

On finished tile, a diameter that's only “close enough” can still leave a very visible problem.

Check the 25mm Cutting Depth

Sutton specifies a 25mm cutting depth for the H115 range.

Compare this with the complete workpiece before starting. Surface material, backing layers & component geometry can all influence whether the cutter has enough depth to complete the opening properly.

Match the Arbor, Pilot or Guide

The holesaw doesn't work in isolation.

Sutton's H115 cutters use an international thread standard for compatible arbor systems, while relevant Sutton sets can include DA1/DA2 arbors, PD1/PD2 pilots & a cutting guide depending on the kit.

Check the individual product or set contents before ordering rather than assuming every cutter comes with identical supporting equipment.

Plan the Water Supply Before Cutting

Don't wait until the cutter starts getting hot.

Sutton calls for a constant flood of water, so work out how continuous cooling will be maintained before drilling begins.

The cutting method also needs to be appropriate for the electrical equipment, worksite & surrounding environment. Water cooling should never be improvised in a way that creates another hazard.

Keep the Cutting Speed Low

More RPM isn't the shortcut here.

Sutton specifies slow-speed operation for H115 diamond-grit holesaws. Excessive heat threatens the diamond bond, so forcing the cutter harder or running it faster works against the intended cutting method.

Individual Cutter or Set?

Replacing one regularly used diameter? An individual cutter may be the straightforward choice.

Working across several plumbing, electrical, fit-out or maintenance applications? Sutton offers H115 sets covering multiple diameters with compatible supporting components.

Buy around the openings you actually make rather than simply choosing the kit with the highest piece count.

Diamond Grit or Diamond Core? Similar Name, Different System

Sutton offers more than one diamond hole-cutting system, which makes the driving equipment just as important as the word diamond on the product.

The H116 range uses an M14 interface designed around compatible angle grinders. That's a different cutting system from H115 rather than simply another diameter option within the same family.

If you're working with Sutton's M14 diamond-core system,  Grinders & Sanders provides a relevant connection to the equipment category driving that style of cutter.

For replacement work, identify the Sutton series, machine interface & material before ordering. Two cutters can both use diamond technology while requiring completely different equipment & operating methods.

Position the Hole Before You Commit to the Surface

There's very little room for “close enough” when the cutter is going through a finished tile, glass panel or installed surface.

Confirm the fitting position, required clearance & surrounding services before cutting.  Measuring & Layout Tools can help establish accurate positions where the installation requires measurements to be transferred across the work.

A professional setup follows a deliberate sequence:

► Identify the material
► Confirm the fitting or component location
► Establish the finished hole diameter
► Check material thickness against cutting depth
► Mark or guide the opening accurately
► Confirm what's behind the surface
► Arrange continuous water cooling
► Set an appropriate low speed
► Start the cutter under control
► Maintain cooling throughout the cut

A diamond-grit cutter can solve the hard-material cutting problem.

It can't move the hole after you've made it.

Expert Tips for Diamond-Grit Hole Cutting

Keep water on the cut continuously. Sutton specifies a constant flood rather than an occasional splash. Cooling should remain part of the process from start to finish.

Heat is the enemy of the diamond bond. Running too fast, too dry or too aggressively can shorten cutter life. If the bond has already been overheated, backing off afterwards doesn't undo the damage.

Identify the substrate properly. “Stone” isn't one material. Sutton specifically lists marble & soft stone for H115, while other masonry products may call for a different diamond system.

Check finished surfaces carefully before drilling. Tiles, glass & decorative surfaces can be expensive, highly visible & difficult to replace once installed. Confirm the position before committing.

Keep the work stable. Vibration & movement make controlled cutting harder, particularly on brittle materials.

Use the intended guide or pilot arrangement. Getting the cutter established accurately is part of producing a professional finished opening.

Remember the 25mm cutting depth. Correct diameter doesn't automatically mean sufficient depth.

Clear the plug carefully. Sutton's cut-out slots assist plug removal, but the cutter, core & freshly cut edges still need to be handled appropriately.

Know which Sutton diamond system you're using. H115 diamond grit & H116 M14 diamond core cutters aren't interchangeable just because both use diamond cutting technology.
